2 Claims.

This invention relates to weather strips in general, and particularly to what may be termed self-locking and self-guiding resilient weather strips.

The prime object of the present invention is to provide a weather strip construction which not only cooperates with, but combines and connects the frame and a closure therefor, to which the structure is secured, but which will effectively prevent any leakage between the two objects, and which will be practically immune to detrimental eifects to its purpose of weather tightening caused by either shrinkage or swelling of the frame or closure or both, as isusually the case in heretofore designed weather stripping.

Another object of the present invention is to so construct and arrange the various parts of the device as to constantly keep them under tension, thereby providing a perfect contact and consequent seal between the objects equipped with my device.

A still further object of my invention is to provide in a weather strip construction male and female members in which the male member takes substantially the shape of a'coiled-up, substantially spiral structure in which each bent portion is spaced from the other so as to render the entire construction resilient.

Another object of my invention is to so construct and arrange the female member of my structure that the latter in itself is resilient throughout, starting from the place of fixed attachment, to either the frame or the closure, and in which a longitudinal pocket formation is provided for resiliently accommodating the cooperating male member.

A still further object of my invention is to construct the pocket-like structure of the female member so that it comprises a plurality of individual surfaces bent in different places, but in which each of the surfaces is spaced from the adjacent surface and in which a reinforcement is provided which serves as limiting means for a possible sidewise motion of the male member.

A still further object of my invention is to cushion the pocket-like structure of the female member either by providing a resilient extension therefrom, forming an integral part thereof, or by associating with the bottom portion of the female member independent, resilient means in the form of a corrugated resilient strip, all for the purpose of rendering the pocket-like structure of the female member more resilient.

The foregoing and still further objects of my invention will become more fully apparent. from the following description and the accompanying drawing, in which are illustrated a few preferred forms of my invention, but which drawing is not intended to 'limit'me to the exact construction shown, and in which Fig. 1 is a typical cross-sectional'view through a frame and a closure, such as a sash, slidably mounted in the frame;

Fig. 2 is a partial front elevation of the female member with the sash removed;

Fig. 3 is a typical cross-sectional view of a male member;

Fig. 4 is an enlarged cross-sectional view of a female member similar to that shown in Fig. 1;

Fig.5 is a cross-sectional view through a modifled form of a female member;

Fig. 6 is a cross-sectional view of a still other modification of a femalemember;

Fig. 7 is a typical cross-sectional view of a modified form of a male member;

Figs. 8 and 9 are modified forms of female members for accommodating the male member shown in Fig. '7; and

Figs. 10, 11 and 12 illustrate diagrammatical Views of my weather strip structure provided with auxiliary, resilient means secured beneath the pocket-like structure of the female members.

Referring now specifically to the figures, in Fig. 1 there will be seen a portion of a frame l0, equipped with parting strips and moldings such as shown at H and l2, between which slidably operates a closure or sash l3. Secured to frame Ill and below either the molding or the parting strip, but in this case below molding l2, there is attached at M a resiliently mounted female member l5, such as shown in detail in Fig, 4. In interengagement with female member and secured to a cut-out corner of sash i3 is a male member l6, the construction of which is clearly illustrated in Fig. '3. I

Offset from the attaching portion of female member I5, I preferably provide a horizontal portion I! (see Fig. 4), at the other end of which there is formed a reinforcing and limiting rib [8, which forms a lock for the male member 16. Extending from the rib, there is a horizontal por tion l9, terminating in a semi-loop 29, from which the material is turned upon itself at 2|. At the other end of this member, there is provided an offset 22 from which extends towards rib l8 an outer portion 23, which terminates in a bend 24, from which the material is turned inwards into a contacting face 25.

In this way a pocket is formed between rib l8 and outer surface 23, and end portion 25, into more resilient.

member comprises an upright portion which is bent substantially at right angles at 26, from which bend extends a horizontal portion 21, a

downwardly bent vertical portion 28, another horizontal outer portion 29, an upward short portion 30, and an inner contacting portion 3|. The latter is intended to engage the inner portion 25 of the female member. 7

In Figs. 3, 4, 5 and 6, the contacting portions are illustrated to represent straight surfaces in full lines. The broken lines, indicated at 32 and 33, show the possibility of curving these contacting surfaces so as to provide an interlocking arrangement between the male and female members for the purpose of increasing their tensional contact over their full respective areas.

In Fig. 5, there is illustrated a modified form in which the pocketlike formation of the female member is constructed somewhat differently from that shown in Fig. 4, in that the bayonet-like structure 34 is formed opposite rib |8', .and in which, from the bayonet-like structure, extends downwardly beneath the pocket formation, a spring element 35, for the purpose'of rendering the unattached portion of the female. member In this construction; extension 36 of the bayonet arrangement issimilar to the extension shown in. Fig. '4, while in Fig. 6 this extension is eliminated,- and a spring element 31 is directly attached to the outer portion of bayonet formation 38. r Referring. now. to Figs. 7, 8 and 9, the male member shown in Fig. 7 consists of an upright portion -39, an outer horizontal portion. and an inner Contacting portion 4|, spaced from portion. 40. The female member consists of an attaching portion 42, a raised continuation, a bayo net structure 44, which latter is constructed opposite to that shown in Figs. 4, 5 and 6, and which forms a left-hand pock 45, at the right hand of which is again a reinforcing and'limiting rib 46, from which extends a portion 41, terminating in an underslung spring element 48, arranged below the pocket structure.

In Fig. 9, extension 41 of Fig. 8 is eliminated and the resilient element 48connects directly with locking rib $6. In these modifications, the

construction is somewhat simplified as far as the. male member is concerned, but the female member retains all of its characteristics explained in connection with Figs. 4, '5 and 6, except that the construction is reversed.

Referring now to Figs. 10, 11 and 12, there is illustrated in Fig. 10 a male member 49, of aconstruction similar to that shown in Fig. 3, and

a female member 50, resembling the structure shown in Fig. 5 in which, however, a bayonet formation Eiis employed which terminates in a straight appendage 52. Associated with the bayonet structure and engaging the upright portion thereof is an individual corrugated spring element53, adopted to render the pocket formation of the female member resilient.

In Fig. 11 a male member 54 is shown, which is also similar to thatillustratedin Fig. 3, but" reversed, and is in engagement with female member 55, in which the bayonet structure 56- is similar to that shown in Fig. 8. The rib or lock formation 51 is at the right and terminates in a short appendage 58. Engaging the upright portion of the bayonet structure again is illus- 'trated an individual spring element 59, adapted to form a resilient cushion for the pocket-like 1 structure of the female membe I sidewise movement.

surface area assures per-fectcooperation between vantageously employed, in which case an individual resilient element such as shown in Figs. IO, 11 and l2, beneath the pocket structure is used.

From the foregoing description it will be perfectly clear that the male and female members telescope with one another and that their con-' tacting surfaces are so designed as to keep the two members under constant tension and that the male member is locked within the pocket formation of the female member by the reinforcing rib illustrated, and that the sidewise movement of the male member is therefore limited at by the rib. When an intense contact between the contacting surfaces is desired, the inner surfaces of the male and female members are curved as shown in broken lines in Figs. 3 to 6, whereby these, members are further restrain-ed against 'Such contact over a' large the two members and results in long life and effectiveness of the device, irrespective of changes due to shrinkage or swelling of the objects to which they are'secured and which they are intended to tightly conditions. I

It is obvious that the male member or female member may be secured either to the stationary or movable portion of a window, depending upon the size thereof and its particular location. By the same token, it is not necessary to secure my device in the manner shown in Fig. 1, but it may be attached at eithercorne'r or on either side of the'sash, as long as a suitable cooperation between female and male members is assured.

While I have shown specific constructions of my invention, it is quite evident that changes and modifications in the formation of the two connect against all weather members may beprovided in order to meet various existing conditions and constructions of the objects to which they are to be attached and I therefore reserve for myself the right to make changes and improvements within my construction without departing from the broad scope of my idea, as set forth. in the annexed claims:

I claim: i

1. In a resilient Weather strip construction,.a resiliently mounted female member comprising a reinforcing rib formation and a pocket-like structure opposite thereto, said structurehaving a resilient, substantially bayonet shaped retaining element consisting of spaced and looped surfaces, rendering it resilient, cushioning means extending from said female member and arranged substantially below said pocket-like structure, and a resilient male member comprising a substantially spirally looped structure in engagement with said pocket-like structure of the female member, the inner contacting faces of the male and female members being constructed and 7 of the female member serving as limiting stop for the sidewise movement of said male member.

2. In a weather strip for Windows, adapted to be unafiected by either shrinkage or swelling of the window frame or sash, and being intended for limiting a lateral movement of a sash in respect to its frame, a female member having a substantially fiat attaching portion, designed to be secured to the face of a window frame adjacent to the side of a sash, a rib formed from said attaching portion and projecting at substantially right angles towards such sash, a substantially pocket-like convolution formed adjacent to, and with its open end towards one side of said rib, a male member, having a substantially fiat attaching portion, adapted to be secured to one of the sash faces, a convolution formed at right angles to that attaching portion and tensionally and slidably interlocking with the convolution of the female member so that said rib of the latter member constitutes a stop against a sidewise movement of the male member.
